HANDLE FOR COUPLINGS 0F AIR-BRAKES.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed February 24, 1914. Serial No. 820,616.

To all whom it may concern:

Be it known that I, CLAUDIUS M. PETTEY, a citizen of the United States, residing at Oxford, in the county of Granville, State of North Carolina, have invented certain new and .useful Improvements in Handles for Couplings of Air-Brakes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in. hose couplings, particularly that class used in connection with the train line of a railway train.

The object of the present invention resides in the provision of means associated with the parts of a two-part coupler of the class described, whereby the parts of the coupler may be readily disengaged. In using these couplers on a train, it is necessary for the operator to crawl under the cars and grasp the coupler, with the consequent discomfiture and danger and it is the design of this invention, that the said means for disengaging the parts of the coupler may be actuated without the necessity of the operator crawling under the car.

A further object of the invention resides in the provision of a device of the class de scribed which may be associated with that formof couplers now in use, without sacrificing any of the advantages thereof and without materially increasing the cost of manufacture of said couplers.

In carrying out the afore-mentioned ob jects, the invention consists in handle portions which extend upwardly from the'tops of both of the two elements of the coupler and which have their free ends directed together and disposed in lapped relation when the elements of the coupler are engaged. Thus to release'the coupler it is merely laterally directed end portions of the handles and pull upwardly to thus rock the elements of the coupler so that they disengage.

If desired, insteadof using the fingers, the.

operator may simply insert the bill of a hook-shaped tool under said end portions and pull upwardly to break the engagement of the coupler elements. 7

Reference is had to the accompanying drawings wherein similar characters of reference designate corresponding parts throughout the several views, and in which:

Figure 1 is a side elevation of a conventional form of coupler, with the improved handles associated therewith, and Fig. 2 is a top plan view of the structure shown in Fig. 1.

Referring now more particularly to the accompanying drawings, A and B designate the two parts of a conventional form of coupler, which have secured thereto the flexible portions 5 of the train line. In this form of coupler it is understood that communication is established through openings in the engaging side faces of the parts.

The handles for releasing the coupler bars comprise stems 6 extending upwardly from the top faces of the parts and having at their upper ends lateral extensions 7 which overlap when the parts A and B are engaged.

From the foregoing it is observed that an exceedingly simple and efficient device which will perform the functions normally required thereof-and which as is observed do not retract from the efliciency of the coupler.

l/Vhat is claimed is: Thevcornbination with the parts of a twopart train line coupling having said parts adapted to be disengaged by swinging them upwardly, of handle portions for the parts comprising members extending upwardly from the tops of the parts and having their upper ends beveled and directed inwardly toward each other and disposed in lapped relation to prevent downward movement of the parts of the coupling when engaged, whereby upward movement of said handle portions with the hand or a tool will simultaneously swing the coupling members into disengagement.

In testimony whereof, I affix my signature, in the presence of two witnesses.

CLAUDIUS M. PE'ITEY.
